Class and type

  • Class and type: Inorganic, simple, solid nitrogen fertilizer
  • Name within the type: UREA


  • Nitrogen (N) 46% /-0,4% – (NH2 – amide nitrogen)
  • Biuret max 1,2%

Carbamide is the most concentrated solid nitrogen fertilizer, characterized by immediate and long-term effects. It contains nitrogen in amide form that is transformed in ammonium and nitrate forms in the soil, through processes of fermentation and nitrification, and therefore is a time-released fertilizer.

In the metal industry carbamide derivatives, mixed with other chemicals, are used as corrosion inhibitors. Carbamide is widely used in the fields of medicine and stomatology due to its strong bacteriostatic, bactericidal, fungicidal and antiseptic effects on gram-positive and gram-negative microorganisms.

Recommended quantities, period and method of application

Types of crops and soil: For complete nitric nutrition of all types of crops and in all types of soil, according to nutritive requirements of plants and physical and chemical properties of the soil.

Quantities to apply: from 100 to 300 kg/ha over the soil for the complete nutrition of crops over the year or for additional nutrition by applying to leaves (foliar feeding) using the solution concentration 0,5-2%.

Application period: For basic soil preparation (50 to 100 kg/ha), pre-sowing fertilization (100 to 300kg/ha) or to reinforce nutrition (100 to 200 kg/ha) and for foliar feeding during intensive vegetation.


Wheat Quantity kg/ha: 100-150
Maize Quantity kg/ha: 110-160
Sunflower Quantity kg/ha: 80-120
Fruit Quantity kg/ha: 200-250

Method of application: Over the soil, by spreading evenly over the whole area, and then mixing it with soil during basic soil preparation or pre-sowing soil preparation. To reinforce nutrition of winter crops – surface application while the soil temperature is below 100C, and to reinforce nutrition of spring crops – incorporation of fertilizer into the soil is recommended.

Number of applications per year: 1-3 times over the soil or 1-2 times in case of foliar application.

Possible adverse effects: if applied in recommended quantities and according to the recommended method of application, there are no adverse effects on the treated crops.

  • In case of long-term application of urea on the same fields with already acidic soils, because of its physiologically acid reaction, the use of equivalent amounts of limestone is recommended (per every 100 kg of urea 85 kg CaCO3), to prevent further soil acidification.
  • Avoid surface application of urea, especially on calcic soils, when there is not a sufficient amount of moisture in the soil and when the temperatures are above 100C, because of the possible nitrogen losses through volatilization.
  • The use of larger quantities of UREA (more than 100 kg/ha) with seed – basic fertilization, may result in certain adverse effects on young plants.

Packing and storage: The fertilizer is stored and kept in dry storage areas protected from the sources of heat, moisture and exposure to the atmosphere in stacks up to 2 metres high.
